ESH Added Pb-Free logo to top of front page
Added CY7C4291V-15JXC, CY7C91V-10JXC, CY7C4281V-10JXC,
CY7C4271V-10JXC, CY7C4261V-10JXC, CY7C4261V-15JXC to ordering infor-
mation.
*C 2896378 03/19/2010 RAME Removed inactive parts from Ordering information and updated package diagram.
*D 2906525 04/07/2010 RAME Removed inactive part from Ordering Information table.
*E 3069396 10/22/2010 ADMU Corrected data in Programmable Flag (PAE, PAF) Operation:
a) PAF is synchronized to the LOW-to-HIGH transition of RCLK by one flip-flop and
is LOW when the FIFO contains n or fewer unread words. Changed PAF to PAE.
b) PAE is synchronized to the LOW-to-HIGH transition of WCLK by one flip-flop and
is set LOW when the number of unread words in the FIFO is greater than or equal
to CY7C4261 (16K-m) and CY7C4271 (32K-m). Changed PAE to PAF.
Added Acronyms, Document Conventions, and Ordering Code Definition.
*F 3210221 03/25/2011 ADMU Removed CY7C4271V-10JC part from Ordering Information table.
